Font Handling and Enhancements

ESC [ p1; p2 SP B GSM (Graphic Size Modification): This sequence modifies the vertical <p1> and horizontal <p2> size of expanded and oversize characters. When using expanded characters, the currently selected font style is used. Oversize uses its own distinct font style.

Parameter values are percentages of the normal size character, so values over 100 are needed for expansion. Expansion factors are obtained by dividing values by 100.

Example: A parameter value of 526 would be divided by 100 to produce an expansion factor of 5 (5X expansion). Values less than

100 are treated as 1X expansion.

X1: 0-199 (Default) X4: 400-499 X7: 700-799

X2: 200-299

X3: 300-399

X6:

500-599

X8: 800-UP

Mixed sizes within a line can be top or bottom justified depending on the Program Mode menu option (see VExOpt:Default and

VExOpt: Baseline).

The top of an expanded character is used as the starting point for vertical paper movement (line feed). The top or bottom of oversize characters can be used depending on the state of menu option

When this sequence is received with a value of 200 or more, expanded printing starts if the printer is in the text mode (not bar codes, oversize, etc.

During vertically expanded printing, blank lines (lines with no printed characters) are not expanded from the current lpi setting.

ESC [ p1 ; p2 SP G SPI (Spacing Increment): This sequence is used to set line spacing

(p1) and character spacing or pitch (p2). If the parameter is missing or zero, the spacing remains unchanged. In the native mode, p1 can range from 1 to 17,820 decipoints (24 inches). The printable area

(between the top and bottom margin) can not be exceeded. The range of p2 is dependent on the font and will be ignored if exceeded.

One font designator plus any number of enhancements can be entered in the escape sequence using the parameter values in the following table. If the requested font is not installed, the default font is selected.

GENPRM (Proportional Print Mode): Enables proportional printing.

This mode does not apply to the oversize character feature. When reset (default), characters are spaced at the current cpi.

GENC1C (C1 Control Code Mode - PC Set 1): When set, it allows the use of C1 control codes. When reset, 80H - 9FH are ignored. See

Appendix E for an explanation of how character sets are mapped. The default state is set using ANSI emulation option 6 (see Appendix D,

ANSI (4800) or ANSI (4410) Tables).

GENSC2 (Character Set 2 Mode - PC Set 2): Selects character set 2 of any of the 8-bit international character sets. See PC Set 2 in

Appendix H for an explanation of how character sets are mapped. The default state is set using option strap 7 in the ANSI emulation options (see Appendix D, ANSI (4800) or ANSI (4410) Tables).

EXAMPLE: To print proportional, send ESC [ > 1 h.

GENDFC (Download Font Control): Using the serial interface, this command allows the host to see if at least one valid font is loaded

(p1=2). The printer sends DCS 30H 30H ST if a font is loaded,

DCS 44H 45H ST if no font is loaded. It also provides the capability to erase the download font area (p1=1).
